Cl. 1338 8 Claims ABSTRACT OF THE DISCLOSURE A coil stacking assembly for use with a coin wrapping machine wherein means are provided for preventing coins in a coin stacking cavity from passing through the side opposite to the coin take-out opening.

Background of the invention The present invention relates to a coin stacking cylinder assembly adapted to be used in a coin packaging machine by which coins are stacked into cylindrical shape and wrapped with a wrapping sheet material.

A conventional coin stacking cylinder assembly is composed of a pair of cylinder halves adapted to form a cylindrical stacking cavity when put together and each having a transversely extending arm fixed to one side thereof, said transversely extending arms of both of the cylinder halves being hinged together at their ends. Such being the construction, should a stack of coins collapse due to misalignment of the coins in the coin stack when the cylinder halves are opened to provide for the removal of the coin stack from the coin stacking cylinder assembly, the coins often drop into the machine through a gap between the pair of transversely extending arms which are fixed to the respective cylinder halves.

Summary of the invention The object of the present invention is to provide a coin stacking cylinder assembly which is free from the foregoing drawback.

According to the present invention, a coin stacking assembly is provided, which assembly comprises first and second members having internal concave surfaces facing one another, and means pivotably connecting said members to enable the members to be relatively moved between closed and open positions, said concave surfaces in said closed position cooperatively defining a substantially cylindrical cavity adapted for accommodating a stack of coins, said members in the open position defining an opening for the removal of coins from said cavity, said members including respective portions extending from said concave surfaces which overlap and cooperate to form a continuous surface in continuation of the concave surfaces opposite said opening as the members are moved towards said open position and thereby prevent coins in said cavity from passing between the concave surfaces on the side opposite said opening.

Brief description of the drawings FIGURE 1 is a plan view of a conventional coin stacking cylinder assembly, the position of said cylinder assembly when opened for the removal of a coin stack being indicated by the dotted lines; and

FIGURE 2 is a plan view of the coin stacking cylinder assembly according to the present invention.

Description of the preferred embodiments Referring to FIG. 1, the conventional coin stacking cylinder assembly comprises a pair of cylinder halves 1 and 2 each defining a respective elongate semicylindrical concave surface 1a, 2a and carrying an arm 3 or 4 extending transversely from one side thereof. The arms 3 and 4 are pivotally connected to the machine frame at one end thereof by means of pins 5 and 6- respectively. Thus, the cylinder assembly may be operated from a closed position indicated by the solid lines to an open position indicated by the dotted lines or vice versa, by such means as a link 7 which is articulated, for example, to the arm 4. Upon completion of coin stacking operation, the coin stack formed is gripped at both the upper and lower ends by a known coin stack gripping mechanism and the cylinder assembly is opened as shown by the dotted lines in FIG. 1, so that the coin stack may be taken out in the direction of the arrow A. In this case, misalignment of the coins in the coin stack may possibly result in collapse of the stack when said coin stack is gripped by the gripping mechanism. When the collapse occurs in the open position of the cylinder assembly, part of the coins constituting the coin stack falls into the machine through a gap between the arms '3 and 4 in the direction of the arrow B and it is not an easy task to retrieve them.

Such drawback of the conventional coin stacking cylinder assembly can be eliminated by the inventive coin stacking cylinder assembly illustrated in FIG. 2.

The coin stacking cylinder assembly according to the present invention, as shown in FIG. 2, is composed of cylinder halves 8 and 9, each defining a respective elongate scmicylin'drical concave surface 8a, 9a and formed at one side thereof with a hinge portion 8b or 912. The cylinder halves 8 and 9 are connected with each other at the respective hinge portions 8b and 9b by means of a hinge pin 10, with the semicylindrical concave surfaces 8a and 9a confronting each other. The cylinder assembly may be opened from a position indicated by the solid lines to a position indicated by the dotted lines by a suitable link mechanism not shown.

An L-shaped arm 11 is connected at one end to the side wall of the cylinder half 8 by screws and carries at thefree end portion of a stop screw 12 whose head is in engagement with a polygonal cam 14 securely mounted on a pin 13. Thus, it will be understood that, by selectively setting the cam 14 in a suitable position by rotating the pin 13, it is possible to determine the diameter of the stacking cavity to be formed by the semicylindrical concave surfaces 8a and 9a, in accordance with the size of the coin to be processed.

As may be clearly seen from the illustration of the figure, with the inventive coin stacking cylinder assembly, coins will not fall into the machine even if the stack of coins collapses in the open position of the cylinder assembly, indicated by the dotted line, provided for the removal of the coin stack therefrom.

What is claimed is:

1. A coin stacking assembly comprising first and second members having internal concave surfaces facing one another, means pivotably connecting said members to enable the members to be relatively moved between closed and open positions, said concave surfaces in said closed position cooperatively defining a substantially cylindrical cavity adapted for accommodating a stack of coins, said members in the open position defining an opening for the removal of coins from said cavity, said members including respective portions extending from said concave surfaces which overlap and cooperate to form a continuous surface in continuation of the concave surfaces opposite said opening as the members are moved towards said open position and thereby prevent coins in said cavity from passing between the concave surfaces on the side opposite said opening, and means for adjusting the closure of said members and thereby the size of the cavity in said closed position, the latter means including a stop means for the closure of said members and an adjustment means cooperating with said stop means for varying the closure of said members.

2. An assembly as claimed in claim '1 wherein said means connecting said members comprises a hinge pin joining said portions of said members.

3. An assembly as claimed in claim 2 wherein one of said portions includes a rounded surface and the other portion includes a planar surface which is in tangential contact with said rounded surface in said open and closed positions and in all positions therebet-ween.

4. An assembly as claimed in claim 3 wherein said rounded surface extends smoothly from the concave surface of said one portion and said planar surface extends at an angle from the concave surface of the other portion.

5. An assembly as claimed in claim 2 wherein said portions include respective surfaces which tangentially contact each other in the closed position and remain in tangential contact as the members are moved to open position to form said continuous surface opposite said opening.

6. An assembly as claimed in claim 1 wherein said adjustment means is a rotatable cam having a plurality of surfaces for individually contacting said stop means to adjust the closure of said members and vary the diameter of said cavity.

7. An assembly as claimed in claim 6 wherein said stop means is secured to a first of said members for movement therewith, said cam being supported in the path of travel of the stop means.

8. An assembly as claimed in claim 2 wherein said portions extend from the members opposite the location where said opening is formed.
